METHOD OF AND MEANS FOR SEVERING AND FEEDING A WEB OF FLEXIBLE MATERIAL3 Shets-Sheet 3 Filed March 28, 1955 g INVENTOR 15 0M fiwa ATTORN EYPatented July as, 1936 GE F E METHOD or AND MEANS FOR SEVERWG ANDFEEDING A WEB OF mamas MA- TEREAL invention relates to a method of andmeans for severing and feeding a web of flexible material, and has forits main object and feature the accurate and speedy production of coversfor a match-books from a web and the feeding of such covers to theconveyer of a match-book machine of the type shown for instance in myapplication Ser. No. 11,269 filed March 15, 1935.

In the accompanying drawings the invention is shown in a concrete andpreferred form in which:

Fig. 1 is a top plan view of a device embodying the invention;

Fig. 2 is a view partly in side elevation and partly in section of thedevice shown in Fig. 1;

Fig. 3 is a perspective fragmentary view of the feed-table, deflectingmember and knife;

Fig. 4 is a transverse vertical sectional view substantially on theplane of line H of Fig. 2; and

Fig. 5 is a more or less diagrammatic perspective view of the feedingand severing elements of the device.

I0 indicates a feed-table, the outer end of which is provided with acutting edge H, and

I2 is a recess in the side of the table, the purpose of which willappear later. Below said'feedtable and forwardly thereof isa support l3to receive a sheet or section from table l6. l4 indi- 3 cates a knife tocooperate with edge l l to sever a section from a web fed along tablel0, and

I5 is a deflecting member to deflect a portion of the web into recessl2. Knife l6 and deflecting member I5 are mounted on a slide l6 recip-35 'rocating in guides 11, and slide I6 is actuated from rockshaft illby means of connections I9.

26 indicates a cover conveyer, the upper run of which is on a level withsupport l3. Said conveyer is here advanced intermittently step by 40step by suitable means (not shown), and it will be noted that support I3is cut away at 2! to permit feed dogs 22 to pass up through said supportto engagethe back edge of the sheet and carry it along. 23 arereciprocating meml5 bers sliding in the framework, and provided withprojections 24 to feed a sheet from support l3 'onto conveyer 20. 25indicates a rockshaft actuating the members 23 by means of connection26, and actuating the rockshaft l8 by means of 0 connections 21.Rockshaft 25 is actuated from eccentric 28 by means of connections 29,and eccentric 28 is mounted on shaft 30 carrying gear 3| receiving itsmotion from gear 32 on shaft 33. 34 indicates a pair of feed rollershere driven 5 continuously to feed web W forward from a web roll (notshown) to provide a slack and pendent portion W in the web. 35 and 36indicate a pair of intermittently acting feed rollers to alternatelyfeed and release the web, and it will be noted that one of said rollers,here 36, is mutilated or has high and low spots as shown, the web beingfed forward when high spot of 36 engages 35, and being released when thelow spot of 36 comes opposite 35. Any suitable means are employed tocontinuously drive rollers 34, 35 and 10 36, such, for instance, assprocket chain 31 passing over sprockets 38, 33, 40 and M.

Web W is severed partially at W before it is fed through rollers 35 and36, and this may obviously be done while the web is in transit from 35its roll, or it may be done by a separate operation and the web rewoundinto roll form. This partial severance W is transversely of the web atone of its side edges and is at predetermined points in the length ofthe web, partial severg0 ance or slit W defining the size of the coveror sheet to be completely severed from the web. 5 Said web is threadedthrough rollers 3d, 36and 36 with a slack portion at W as indicated inFig. 2, and the forward end of the web placed 5 on feed-table l0.Rollers M-maintain slack and pendent portion W in the web, and rollers35 and 36 draw intermittently from said slack portion and advance theweb along feed-table it. The high and low-spots onlroller 36 are of suchso length and the speed of rotation of rollers 35 and 36 are socalculated and. timed that with each intermittent feeding movement ofsaid rollers an amount of web in excess of the length defined by thedistance between slits W is ad- 35 vanced. In so advancing the web, thepartially severed portion of the web passes over recess i2 and, when therear end of the forward web section is above said recess, deflectingmember i5, the face of which is in line with that of knife id, 40descends deflecting said partially severed portion into recess l2thereby blocking the web when the undeflected portion of the nextsucceeding web section encounters the face of the deflecting member.Rollers 35- and 36, however, continue momentarily to feed the remainderof the web whereby a buckle W is formed in said remainder of the web. Atsubstantially the same time that the undeflected portion of the nextsucceeding web section encounters the face of the demember, the partialline of severance reaches the plane of the cutting edge of knife I 4 andthe latter almost immediately completely severs the web in line with thepartial severance, and this action also tends to blockthe web and tocreate the buckle aforesaid as rollers 35 and 36 still continue to urgethe remainder of the web forward. Rollers 35 and 36 now release the weband the weight of slack W retracts the web a certain distance and buckleW disappears. The object of the slight overfeed caused by rollers 35 and36 is to render certain that sufficient web is always fed so that acover of proper size will be severed from the web, defleeting member l5and knife l4 preventing too large a cover from being severed from theweb. In order to prevent buckle W from being formed too closely adjacentto the cutting devices, cover plates 42 may be arranged above table illin closely spaced relation thereto and, if desired, spring-pressedplungers 43 or light springs may be carried by slide Hi to bear upon thepaper and prevent slack W from retracting the web too far. The deflectedportion W regains its shape and is not permanently deformed out of theplane of the web or sheet, and to assist the severed sheet W in passingto support l3, ejectors 44 carried by slide l6 may be used. Members 23now advance and sheet W is transferred to conveyer 20 of the match-bookmachine.

I claim:

1. The method of severing a web of flexible material into predeterminedlengths which consists in: partially severing the web transversely at apredetermined point in its length; advancing said web an amount inexcess of that defined by its partial severance; deflecting thepartially severed portion of the advancing web and completely severingit in line with its partial severance thereby causing a buckle to beformed in the remaining and advancing portion of the web; and retractingthe buckled portion of the web.

2. The method of severing a web of flexible material into predeterminedlengths which consists in: partially severing the web transversely atpredetermined points in its length; intermittently advancing said web anamount in excess of that defined by its partial severance; deflectingthe partially severed portion of the front section of the advancing weband completely severing it in line with its partial severance therebycausing a buckle to be formed in the remaining and advancing port-ionsof the web; and, intermittently and alternately with the advance andcomplete severance of the web, retracting the buckled portion of theremainder of the web.

3. The method of severing a web of flexible material into predeterminedlengths which consists in: partially severing the web transversely at apredetermined point in its length; maintaining a slack and pendentsource of supply of said partially severed web; advancing said web fromsaid slack supply an amount in excess of that defined by its partialseverance; deflecting the partially severed portion of the advancing weband completely severing it in line with its partial severance therebycausing a buckle to be formed in the remaining and advancing portion ofthe web and stopping the advance of said remaining web portion therebyallowing the weight of said slack and pendent source of supply topartially retract the buckled portion of the web.

4. The method of severing a web of flexible material into predeterminedlengths which consists in: partially severing the web transversely atpredetermined points in its length; maintaining a slack and pendentsource of supply of said partially severed web; intermittently advancingsaid web from said slack supply an amount in excess of that defined byits partial severance; deflecting the partially severed portion of thefront section of the advancing web and com- 1 pletely severing it inline with its partial severance thereby causing a buckle to be formed inthe remaining and advancing portion of the web; and, intermittently andalternately with the advance and complete severance of the web, ai- 1lowing the weight of said slack and pendent source of supply topartially retract the buckled portion of the web.

5. A web severing and feeding device including: a feed-table having acutting edge at its out- 20 er end and a recess at its side; means tofeed a web partially severed at predetermined points, along said table,the partially severed portion of the web passing over the recessaforesaid; a deflecting member to deflect the partially severed portioninto the recess aforesaid while the web is moving; and a movable knifeto complete the severance of said web in line with its partialseverance.

6. A web severing and feeding device including: a feed-table having acutting edge at its outer end and a recess at its side; intermittentlyacting means to alternately overfeed and release a web, partiallysevered at predetermined points, along said table, the partially severedportion of the web passing over the recess aforesaid; means to maintaina slack and pendent supply of said web for the use of the intermittentlyacting means; a deflecting member to deflect the partially severedportion into the recess aforesaid while the web is moving; and a movableknife to complete 'the severance of said web in line with its partialseverance.

'7. The method of severing a web of flexible material into predeterminedlengths which consists in: partially severing the web transversely atone of its side edges at predetermined points in its length; advancingsaid web an amount in excess of that defined by the distance betweensuccessive lines of partial severance; de-

fleeting the partially severed portion of the advancing web beforecompletely severing it and completely severing said advancing web inline with its partial severance, thereby causing a buckle to be formedin the remaining and still advancing portion of the web; ,and retractingthe buckled portion of the web. 8. A web severing and feeding deviceincluding: a feed-table having a cutting edge at its outer end and arecess at its side; means to feed a web partially severed atpredetermined points, along said table, the partially severed portion ofthe web passing over the recess aforesaid; a movable knife to completethe severance of said web in line with its partial severance; and adeflecting member to deflect the partially severed portion of the webinto the recess aforesaid-while said web is moving and before the lineof partial severance reaches the knife. 7
